IR2177SPBF - Phase Current Sensor IC

Download the IR2177SPBF datasheet PDF. This datasheet also covers the IR2277S variant, as both devices belong to the same phase current sensor ic family and are provided as variant models within a single manufacturer datasheet.

Description

IR2177/IR2277 is a high voltage, high speed, single phase current sensor interface for AC motor drive applications.

The current is sensed by an external shunt resistor.

Features

  • Floating channel up to 600 V for IR2177 & 1200 V for IR2277.
  • Synchronous sampling measurement system.
  • High PWM noise (ripple) rejection capability.
  • Digital PWM output.
  • Fast Over Current detection.
  • Suitable for bootstrap power supplies.
  • Low sensing latency (.
